Options to Upgrade/Replace my Sonos Connect Gen2 & Troubleshooting for Repair

Greetings SONOS forum,

My Connect Gen2 is dead only after 3 years of service.  The SONOS support states I can get a replacement for $279.00 since my unit is out of warranty.  My unit factory resets to a blinking white light with occasionally a flicker of amber.  While holding the Play button a distinct Amber light blinks about three times and then white, then cycles.  Prior to it completely not working, the unit starting sending a low background thumping sound and was dropping out.  I would reset it and then it would work for a bit more but then drop out.  Setting aside having my electronic guru fix it (he can), what product will I get as a replacement?  That was not made clear to me.  Another Connect Gen2 or a newer product?  I can upgrade at 15% off but upgrade to what?  Seems odd to me that products only last 3 years.  I can understand software and firmware support compatibility issues emerging fast making things obsolete but hardware like capacitors and power supply components should not last just 3 years!--only needed to last 1-year I guess.

I just need to connect my old stereo equipment so I can listen to my own speakers through my old components as well as SONOS speakers in other areas of the house. I don’t need an Amplifier.

Should I fix, upgrade or replace?  My Great American Sound (GAS) equipment is still working just fine:).
